RADIATOR.

Specification of Letters Patent.

Patented Feb. 3, 1920.

Application filed August 6, 1917. Serial No. 184,562.

To all whom it may concern:

Be it known that I, SAMUEL BOWMAN, a citizen of the United States,residing at Redondo Beach, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inRadiators, is a specification.

'My invention relates to radiators such as are used on automobiles forcooling the water to the engine and the objects of my invention are,first, to provide a radiator which is simple and economical ofconstruction, second, to provide a radiator of this class which is easyto repair, third, to provide a radiator of this class which is verystrong and durable and Will not be materially affected by the wrenchingeffect of running over rough ground, fourth, to provide a radiator ofthis class which isapplicable for and may be readily laced in positionin the differentshaped radiator supports for the various makes ofautomobiles, and fifth, to provide a radiator of this class action andwill not get out of order.

With theseand other objects lIhVleW as will appear hereinafter, myinvent1on consists of certain novel features of construc tion,combination and arrangement of parts as will be hereinafter described indetail and particularly set forth in the appended claims, referencebeing had to the accompanying drawings and to the characters ofreference thereon which form a part of this specification in which:

Figure 1 is a rear elevatlonal view of my radiator shown mounted inposition in the front end of the hood and showing the water receptaclein connection therewith and showing a portion broken away and in sectlonto facilitate the illustration; Fig. 2 is 'a side elevational viewthereof and showing a portion broken away and in section to facilitatethe illustration; and Fig. 3 is a sectional view on an enlarged scaleshowing a portion of the radiating section in detail.

Similar characters of reference refer to similar parts throughout theseveral views of the drawings.

The supporting band 1, annular tubes 2, corrugated spacers 3, waterconductor 4, water conductor 5, frame 6, receptacle 7, tube connection8' and tube connection 9 constitute the principal parts of my radiator.

readily deteriorate or of which the following oods or which is veryeflicient in its- The supporting band 1 is a circular metallic band ofsuitable size for the outer tube 2 to rest therein and the remainder ofthe tubes 2 are placed concentric with each other and spaced apart fromeach other by means of the corrugated spacers 3 which permit the air'topass through between said tubes and the water in said tubes is cooled byradiation from the metal of said tubes and these corrugated spacers.

It will be here notedthat these tubes 2 are fiat and made from twopieces which pieces overlap each other at the front and ack edges wherethey are soldered together as shown best in Fig. 3 of the drawings thusproviding double strength at the edges where great strength is required.

The inlet and outlet conductors 4 and 5 to and from said tubes 2 tapertoward the center so as to provide the proper proportion of water totheouter tubes as to the inner ones in proportion to their area. Thesetubes 2 have inlets 2 from the conductors 4 and outlets 2 connectingwith the conductor 5 so that the water circulates through approximatelyone-half. of each tube in opposite directions so that each tube is ineffect a double conductor of semi-circular form. This supporting band 1is look seamed in and the ends 1 left apart and serve as clamps forsecuring said band 1 to the outer tube 2. Mounted on the top of saidsupporting frame 6 is the water receptacle 7 which is preferably thesame shape as the ordinary 'or conventional receptacle for water for aradiator and it isprovided with an inlet port 7 for pouring the waterinto the radiator. The supporting frame 6 is'provided withreinforcements 6 and 6" which extend outwardly and serve as lugs 6 whichrest onthe side frames of the vehicle. Connecting with the waterreceptacle 7 is'the return hose connection 8 and connecting withthe/connection 5 is the exit hose connection 9 so that the watercirculates from the lower end of the connection 5 through the engine tothe hose connection 8 and into the water receptacle 7 therein into theconnection 4 and into the tubes 2.

Though I have shown and described a particular construction, combinationand arrangement of parts, I do not wish to be limited to this particularconstruction, combination and arrangement but desire to include in thepurview of my invention the construction, combination and arrangementsubstantially as set forth in the appended claims. v

It is obvious that with this construction, there is provided a radiatorin which the water circulates in certain semi-circular confined channelsfrom the top to the bottom of the radiator therein through the engine tothe top again; that the inlets to the separate tubes are of a sizeproportional to the surface area thus permitting only a certain quantityof water to pass into said tubes so that all are cooled equally; thatthe tubes being circular in a form provide great strength anddurability; that the structure as a whole is very simple and economicalof construction, durable and will not readily deteriorate or get out oforder.

Havin thus described my invention,

what I c aim as new and desire to secure by Letters Patent, is: v

1. In a radiator, a plurality of circular tubes concentrically spacedapart from each other, said tubes having inlets and outlets proportionalto the surface area of said tubes, means for conducting water to andfrom. said inlets and outlets and means for holding said tubes incertain spaced relation to each other consisting of corrugated metallicmembers.

2. In a radiator, a plurality of circular tubes concentrically spacedapart from each other, said tubes having inlets and outlets rsaaeerproportional to the surface area of said tubes, means for conductingwater to and from said inlets and outlets and a water receptaclecommunicating with the means for conducting water to said inlets.

3. In a radiator, a plurality of circular tubes concentrically spacedapart from each other, said tubes having inlets and outlets proportionalto the surface area of said tubes, means for conducting water to andfrom said inlets and outlets, a Water recap-- tacle communicating withsaid means for conducting water to said inlets, and means for holdingsaid tubes in certain spaced relation to each other.

4. In a radiator, aplurality of circular ing said tubes and spacingmeans on the frame of the vehicle.

In testimony whereof, I have hereunto set my hand at Redondo Beach,California, this 27th day ofJuly, 1917.

SAMUEL BOWMAN.
